It is incorrect to assert that payload should be at least 16 bytes large in for the "pserop" sertype. That condition is only valid if the topic is keyed, because it only supports keys that are exactly 16 bytes large.

Instead, for an unkeyed topic, anything size is plausible and it is the deserializer that rejects malformed input.

This commit also adds some tests for some variations on the participant message data theme, including one that triggers the assertion. in addition there is a bit of additional checking in constructing a new sertype_pserop.
